How to Apply This:


On the worksheet, you would:
- Circle or underline the subject in red (e.g., “The ocean waves”)
- Circle or underline the predicate in blue (e.g., “roared loudly”)

This helps students visually separate who is doing something from what they're doing.

Tip: Always ask yourself:
- Who or what is the sentence about? → That’s the subject
- What is the subject doing? → That’s the predicate
